Laughed out loud from happiness when I sat in it. I'm about 5'11'' and 210lbs. There's lots of room for movement in it. It feels as sturdy as a tank, just like its name. The padding is perfectly soft and comfortable to sit on/against. It has nice lumbar support. Directions were easy to follow. It took me about 25 minutes to put it together. Reclines easily and also locks into place well. Only downside is it's a bit pricey.

Pretty cool chair. I never built something like this before besides a Lego set but I did it as the manual instructed and it's comfortable and I can lean back and play my PS5 well.

It's incredibly stable, and I'm a reasonably big guy (for you) at 6'2" and 210lbs. Even trying like an idiot to tip it over back and forth and side to side, it doesn't budge. I'd feel comfortable reclining it back and having a nap. The material seems and feels nice enough, it's got metal internal construction, and there are actual bearings. Time will of course tell how the material and padding hold up.
